Our present invention relates to an improved air filter, designed for use w1th the carbureter of internal combustion engines as generally used on automotive vehlcles.

The invention involves the use of a casing or tank with water therein as a filtering medium and the invention also utilizes a fibrous packing, as wool, as an auxiliary filter and drier, for the fuel air as it is drawn from the atmosphere.

The inveution'consists in certain novel combinations and arrangement ofparts involving the above indicated structures as will hereinafter be more fully set forth and claimed. In the accompanying drawings we have illustrated one complete example of the physical embodiment of our inventior. wherein we have illustrated the parts com bined and-arranged according to the best mode we have thus far devised for the practical application of the principles of our invention.

Figure 1 is a view showing so much of an internal combustion engine, its carburetor, and other parts as are necessary to illustrate the relation thereto of the air filter of our e invention.

Figure 2 is an enlarged vertical sectional view of the filter.

Figure 3 is a detail sectional view show 'ing one of the fasteners between the lid or cover and the tank or casing of the filter,

Figure 4 is a detail sectional and partial perspective view of a portion of the perforated partition of the filter tank.

ln order that the general arrangement and relation of parts may readily be understood we have illustrated in Figure 1 a portion of an internal combustion 1 with the standard type of carbureter 2, the intake manifold 3 and the air pipe 4. The air pipe 4 is for en plying the filtered air to'the carburetor i fir mixture with the gas as it passes from the carbureter to the intake manifold, and this ipe, as best seen in Figure 2 is threaded into an opening in the lid or cover 5 of the-water casing 6 of the filter. Air is supplied from the atmosphere to the filter through the supp] pipe 7 and this pipe, which is also secure in the lid 5 terminates at its lower end 8 Within the filter body and is submerged below the water level in the fiilter. A bafile plate 9 is located below the'lower end of the inlet vent it from passing in currents through the perforated partition 10. This partition is located at the bottom of ,the cylindrical part 6 of the filter and is provided with perforations having tapering walls as 11 with the lower walls of the orifices or per forations of smaller diameter than the upper openings. The perforated partition is located between the c lindrical body of the filter and its conical sediment collector or collecting chamber 12. The chamber12 is adapted to collect sediment from ,the'water entering the filter and the battle plate 9 and perforated partition 10 prevent agitation by water currents of this sediment. The perforated partition thus acts as a separator for purifying the water and air, and the latter is so directed that it passes only through the purified water for filtering purposes.

The collecting chamber 12 may be emptied and cleansed b the use of the drain cock 13 located at t e pointed lower end of the filter. v

A reticulated disk 14 is located within the filter at or about the water level to revent splashing of the water and the filter ody is filled to, approximately the water level indicated in Figure 2 through the air inlet pipe 7 when required.

In the upper or top part of the filter, above the water level, we supply a fibrous filtering medium for the air as it emerges from the water (as indicated by the arrows in Figure 2) and this medium indicated by the numeral 15 may be wool or other suitable material that not only filters the'air, but also acts as a drier and retards movement of moisture to the filtered air pipe 4.

The' filtering fibrous material 15 is supported on an open screen as 16 which rests at its edges upon a retaining or supporting ring 17 that is secured to the inner face of the filter, above the water line. A water gage 18 of usual t pe is used on the exterior of the filter to in( icate the water level.

Preferabl the lid 5 is rigid with the carbureter t rough the filtered air pipe 4,

and the filter is detachable from the lid for cleansing, re air, or replacement of parts. By means of a suitable number of spring catches or latches 19 each having a book 20 to engage a keeper-notch 21 in the lid, the

body is suspended or supported from the lid. The spring latches are secured at 22 tov the exterior of the filter body and-the latter is recessed as at 23 to accommodate the latches a bracket 24 that is rigidly secured to a stationar support and the bracket adds to the stabi ity of the supported filter.

It will be apparent that as the air passes through the water and thence through the fibrous filtering medium and drier on its way to the filtered air pipe 4 and the carbureter, all extraneous matter is removed from the air and the latter in a filtered or purified state is supplied to the fuel of the engine or motor,

go Having thus fully described our invendesire to pipe, of a water container and means for detachably securin said container to the lid, a baflie plate in the water chamber below the lower end of the submerged air supply pipe, a perforated partition in the water container below the bafile and a sediment chamber below the-partition, an anti-splash screen, at the water level, a

fibrous packing in the upper end of the container above the water level and a reticulated support for said packing.

In testimony whereof we allix our signatures.
